I'd be wary of *not* touching \efi\boot, since both Microsoft and Linux 
installs \efi\boot\bootx64.efi. And with desktop systems often not 
having an UEFI Shell built in and no option to browse for a boot loader 
from the BIOS, if the FreeBSD boot entry gets lost somehow they're 
stuck. I discovered recently that rEFInd at least knows to look for 
\efi\freebsd\loader.efi, but otherwise recovery could be pretty tricky 
for people who aren't familiar with UEFI. Perhaps adding an option to 
the efi-update-loader script to search for and list potential ESPs could 
help, along with good documentation of efibootmgr etc.
